CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to and the benefit of U.S. Provisional Patent Application No. 62/825,479, titled “WEIGHTED APPAREL SYSTEMS AND METHODS FOR USE IN PERSONAL FITNESS” and filed on Mar. 28, 2019, the content of which is hereby incorporated herein in its entirety.

TECHNICAL FIELD

The disclosed technology is generally directed to systems and methods for improved personal fitness. More particularly, implementations generally pertain to articles of clothing that may be weighted by way of integrated portions and/or weighted portions configured to be coupled with an article of clothing.

BACKGROUND

Previously, users would need to hold weighted units, e.g., dumbbells and/or barbells and/or weight plates, to add weighted resistance during a personal fitness session such as a workout. Such additional weights generally require partial or complete commitment by the user's hands to hold the additional weight. Such restrictions undesirably prevent the user from using his or her hands for other purposed during the fitness session, such as holding a water bottle or an electronic device, for example.

Implementations of the disclosed technology address these and other limitations in the prior art.

DESCRIPTION

Implementations of the disclosed technology are generally directed to methods, techniques, and systems for a user to add weight during a personal fitness session, e.g., to increase the personal workload to create physical benefits through such personal training and physical activity. The weights may be either embedded (e.g., by way of weighted yarns and/or fabrics) or added onto a product (e.g., by way of magnetic weight sheets or weighted layers and/or shells) to a portfolio of products such as articles of clothing configured to be worn by a user during personal fitness sessions.

The disclosed implementations represent a new category of functional fitness gear that is based on the insight that adding load onto a user's body while working out maximizes the effect, builds strength and endurance, and burns more calories for the user. Adding the right amount of weight, distributed in the right places, e.g., close to a person's center of gravity, is an under-leveraged, safe, and effective way of getting more out of every activity.

In certain implementations, regular, e.g., weekly or daily, short and effective workouts may be provided by way of the mobile connection embedded in most personal electronic products such as tablets and smartphones. In addition, wearing such products by a user while doing sport/fitness activities maximizes the effect without adding precious time.

Certain embodiments may include a portfolio of visually attractive, modern, and comfortable weighted apparel products configured to be worn for health, wellness, fitness, and training. Such portfolio may include weighted compression tank-tops, t-shirts, long sleeve t-shirts, jackets, and vests, where the weight may be embedded and completely evenly distributed across the product. In certain instances, the fabric itself may deliver the desired weight, in other instances, additional loads may be added in an evenly distributed manner across the garment.

Certain implementations may include a weighted vest where, rather than creating a vest with pockets simply holding weights, the entire vest may be molded into a single stunning piece of equipment, e.g., constructed by encased steel spheres in varying, corresponding dimensions, anatomically, and evenly distributed across the body. These weighted units may be molded in place within a transparent silicone and/or TPU frame, for example.

The closures and straps may be integrated into the piece, making it a visually stunning product with the additional benefits of the piece being easy to clean because the entire piece may be sealed and thus simply washed and/or rinsed off In certain embodiments, the steel spheres may act as a receiving mechanism for additional weights to be added, e.g., by easily snapping them in place by leveraging corresponding magnets on the supplemental weight sheets.

FIG. 1 illustrates a first front view of a first example of a weighted apparel system in accordance with certain implementations of the disclosed technology. In the example, a user 101 is wearing an article of clothing 100 that is configured to be worn by the user 101 during a personal fitness session. The article of clothing 100 may be selected from the following group: a vest, a shirt (e.g., a compression shirt), a pair of pants, a pair of shorts, a jacket, a piece of footwear, and a piece of headwear.

The article of clothing 100 has multiple portions 102, 104, 106, and 108 that each include a coupling mechanism. The example also includes a first weighted unit 110 having a coupling mechanism configured to interact with the coupling mechanism of a corresponding portion 104 of the article of clothing 100 to cause the first weighted unit 110 to remain substantially in place at the portion 104 of the article of clothing 100 during the personal fitness session.

Alternatively or in addition to the article of clothing 100 having the multiple portions 102, 104, 106, and 108, the article of clothing 100 may have a fabric layer and at least one weighted portion that is formed by either or both polyurethane (PU) and thermoplastic polyurethane (TPU) being printed on the fabric layer. The PU/TPU that is printed on the article of clothing 100 may be patterned and/or sized to achieve a desired weight for the user such as, for example, a certain number of ounces or a certain number of pounds.

The example further includes a second weighted unit 112 having a coupling mechanism configured to interact with the coupling mechanism of a corresponding portion 108 of the article of clothing 100 to cause the second weighted unit 112 to remain substantially in place at the portion 108 of the article of clothing 100 during the personal fitness session. It will be appreciated that the user 101 can use either or both first and second weighted units 110 and 112, separately and/or concurrently, during the personal fitness session.

Alternatively or in addition thereto, either or both of the first and second weighted units may include water and/or sand and/or other suitable material(s) to increase the weight of the weighted unit. Further, while the example only includes two weighted units 110 and 112, it will be appreciated that there is virtually no limit to the number of weighted units and/or corresponding portions of the article of clothing 100. Indeed, in certain implementations, a weighted unit may couple on top of another weighted unit such that the user 101 may layer any number of weighted units at any number of corresponding portions on the article of clothing 100. This advantageously provides the user 101 with the ability to progressively increase the weight during his or her personal fitness session.

In the example illustrated by FIG. 1, the article of clothing 100 also includes two communication units 120 and 130 that are each configured to interact with an electronic device 150 such as a personal computing device, e.g., a tablet or smartphone or other suitable piece of hardware. Here, the first communication unit 120 is a QR code and the second communication unit 130 is a near field communication (NFC) device.

FIG. 2 illustrates a second front view of the first example of a weighted apparel system in accordance with certain implementations of the disclosed technology. In the example, the coupling mechanisms of the portions 102, 104, 106, and 108 of the article of clothing 100 each include a plurality of metal units such as ball bearings 103, 105, 17, and 109, for example.

The ball bearings 103, 105, 17, and 109 may be made of steel and/or other suitable material(s) such as cast iron, for example. In certain embodiments, the plurality of metal units may be embedded within the article of clothing 100 at the designated corresponding portion 103, 105, 17, and 109.

In certain implementations, the ball bearings 103, 105, 17, and 109 may be enclosed spherical-shaped weights that are situated or otherwise positioned between two layers of PU-coated textiles by way of any or all of the following techniques: compression, RF welding, and ultrasonic methods. Such embodiments are advantageously flexible, soft, washable, and generally more appealing than other embodiments such as silicone/TPU alone, for example.

In the example, the first weighted unit 110 includes a plurality of magnetic units, e.g., magnet 111, that are arranged and configured to magnetically couple with the plurality of metal units, e.g., ball bearing 105, of the corresponding portion 104 of the article of clothing 100.

Also in the example, the second weighted unit 112 includes a plurality of magnetic units, e.g., magnet 113, that are arranged and configured to magnetically couple with the plurality of metal units, e.g., ball bearing 109, of the corresponding portion 108 of the article of clothing 100.

It will be appreciated that in alternative embodiments, the coupling mechanism of the first weighted unit 110 may include a plurality of metal units, e.g., ball bearings, and the coupling mechanism of the corresponding portion 104 of the article of clothing 100 may include a plurality of magnetic units that are arranged and configured to magnetically couple with the plurality of metal units of the first weighted unit 110.

Alternatively or in addition thereto, the coupling mechanism of the second weighted unit 112 may include a plurality of metal units, e.g., ball bearings, and the coupling mechanism of the corresponding portion 108 of the article of clothing 100 may include a plurality of magnetic units that are arranged and configured to magnetically couple with the plurality of metal units of the first weighted unit 112.

In certain implementations, either or both of the first and second weighted units 110 and 112 may be made of either or both thermoplastic polyurethane (TPU) and silicone. In such embodiments, the plurality of metal units of the weighted units 110 and 112 may be embedded within the TPU and/or silicon.

FIG. 3 illustrates a front view of a second example of a weighted apparel system in accordance with certain implementations of the disclosed technology. In the example, the user 301 is wearing an article of clothing 300 that may be configured to couple with any number of weighted units so that the user 301 may actively increase—or decrease—the amount of additional weight on his or her body during a workout.

In the example, the weighted portion 1600 includes a main part 1610, that is made of silicone or other suitable material, and a plurality of units, e.g., 1612, that are formed from the main part 1610.

FIG. 17 illustrates a second example of a weighted portion 1700, such as the weighted portions 110 and 112 illustrated by FIG. 1, of a weighted apparel system in accordance with certain implementations of the disclosed technology. In the example, the weighted portion 1700 includes a main part 1710, that may be made of fabric, silicone, or other suitable material, and a plurality of units, e.g., ball bearing 1712, that are integrated with, e.g., woven into, the main part 1710.

In certain alternative embodiments, an article of clothing configured to be worn by a user during a personal fitness session may have at least one weighted portion, e.g., made of either or both steel and silicone, that is integrated with the article of clothing. The weighted portion(s) may include heavy yarn that is knitted into the article of clothing. Alternatively or in addition thereto, the weighted portion(s) may include a plurality of ball bearings that are knitted into the article of clothing. Alternatively or in addition thereto, the weighted portion may include a plurality of weighted tubes that are knitted into the article of clothing.

FIG. 18 illustrates an example 1800 of a weighted article of clothing 1810 in accordance with certain implementations of the disclosed technology. In the example 1800, the weighted article of clothing 1810 includes a plurality of units, e.g., tube 1812, that are integrated with, e.g., woven into, the article of clothing 1810.

Alternatively or in addition thereto, the article of clothing 1810 may be a long-sleeve compression shirt, or other suitable top, having micro-weights evenly distributed therein. The micro-weights may have a weight of 1-2 pounds, for example.

In certain implementations, the user's electronic device may be configured to launch at least one selected from a group consisting of the following: real-time coaching, a training program, and a connection with at least one other user. Upon tapping a mobile phone to an NFC tag, for example, a connection may be established allowing the user to A) Identify, and pair each individual product; B) Register the unique product with us to receive personal additional content, services and offers; C) Unlock daily, live workouts optimized for use with our weighted apparel portfolio; and D) Connect to every other user of the product, thereby creating a unique community opportunity.

FIG. 19 is a flowchart illustrating an example of a method 1900 for using a weighted apparel system in accordance with certain implementations of the disclosed technology. At 1902, a user taps a near-field communication (NFC) tag or scans a QR code on an article of clothing configured to be worn by the user during a personal fitness session. At 1904, the system directs the user to download the corresponding application (App) on his or her electronic device, such as a smartphone, tablet computing device, laptop computer, or other suitable personal electronic device, unless such App had been previously downloaded by the user and installed on the electronic device.

At 1906, the system may present to the user an introductory video that explains the pertinent product(s) and/or service(s). This step is optional and may be skipped or otherwise bypassed by the user, e.g., in the event that the user has already watched the video and does not desire to watch it again.

At 1908, the system may prompt the user to create a personal account. This step may be skipped or otherwise bypassed if the user has already created an account and is still logged into such account on the App, for example.

At 1910, the user taps the NFC tag and/or scans the QR code to associate the pertinent product, e.g., the article of clothing, to the user's account. This results in the system causing the user to land on the App's homepage, as indicated at 1912.

Certain implementations may include a LIVE page, where live sessions may be delivered up to—or even over—5 times per day. Each session may be 10-15 minutes and led by a professional instructor, for example, and designed to maximize the results from working out with added weights.

Completed live session statistics may be saved to the user's account. Users may be logged in to the session to see how many other users are online. The instructor may also see which users are live and encourage participants with real-time shout-outs, for example (e.g., with user consent).

Alternatively or in addition thereto, the App may include a SESSIONS page that has a user's saved “offline” workouts, e.g., from previous personal fitness sessions, that may be accessed and/or used by the user anytime.

Alternatively or in addition thereto, the App may include a ME/account page that may include any or all of the following: the user's workout history, account information, product information, and personal preferences.

It will be appreciated that not every embodiment necessarily includes all of the individual steps 1902-1912. It will be further appreciated that, in certain embodiments, some or all of the steps 1902-1912 may occur in an order that is different from the order in which they are presented by FIG. 19.

In certain implementations, the App on the electronic device may provide a user interface that includes identification information corresponding to the user and multiple other users, e.g., workout partners and/or personal friends that have connected with the user by way of the App. The App may also provide any or all of the following options for the user: to watch a workout session live (“LIVE”); to watch previously recorded workout sessions (“SESSIONS”); to shop for items such as weighted apparel and/or other articles of clothing (“SHOP”); and to communicate with or otherwise contact another person such as a personal trainer (“BEN” in the example).

FIG. 20 illustrates a first screenshot 2000 of an application for a weighted apparel system in accordance with certain implementations of the disclosed technology. In the example, the screenshot 2000 includes. In the example, the screenshot 2000 results from the user selecting the “LIVE” option, and includes information pertaining to a live workout session, e.g., an “I'm In” feature to allow the user to participate in the session, and identification information pertaining to either or both the instructor/trainer and one or more other participating users.

FIG. 21 illustrates a second screenshot 2100 of the application for a weighted apparel system in accordance with certain implementations of the disclosed technology. In the example, the screenshot 2100 results from the user selecting the “SESSIONS” option, and includes at least one suggested workout session by a certain person, e.g., trainer, which is selected by the App based at least in part on the trainers responsible for the user's previous workouts through the App. In the example, the user has previously accessed one ore more workouts through the App that were led by and/or provided by a trainer named Sarah so the screenshot 2100 provides the user with at least one workout session by Sarah.

In the example, the screenshot 2100 also includes at least one suggested workout session that is selected by the App based at least in part on what types of workout sessions the user has previously accessed through the App. In the example, the user has previously accessed running-related workouts through the App so the screenshot 2100 provides the user with at least one running-related workout session.

FIG. 22 illustrates a third screenshot 2200 of the application for a weighted apparel system in accordance with certain implementations of the disclosed technology. In the example, the screenshot 2200 results from the user selecting the “SHOP” option, and provides the user with an interface that the user may use to browse, select, and purchase items such as weighted apparel or other articles of clothing such as those described herein.

FIG. 23 illustrates a fourth screenshot 2300 of the application for a weighted apparel system in accordance with certain implementations of the disclosed technology.
